Wastewater Services
The Water Corporation manages about 90% of Perth and Mandurah’s wastewater through thirteen wastewater systems.
Beenyup, Subiaco and Woodman Point are large wastewater systems that collectively serve more than 1.3 million people in the metropolitan area. Medium sized systems in Point Peron, Kwinana and Gordon Road (Mandurah) service over 100,000 people.
Small wastewater systems in Halls Head (Mandurah), Caddadup (Mandurah) and Pinjarra serve around 15,000 people while four very small plants at Two Rocks, Yanchep, Bullsbrook and Mundaring serve less than 5,000 people.
Any remaining wastewater that is not collected by the Water Corporation is individually managed on site by homes and industry through septic tank and leach drain systems.
